Including today, we have four regular season Friday's left. I am going to use each of those Friday's and this column to target a different group of risers and fallers, with an eye on their value in dynasty leagues going forward. Today we'll go over middle infielders, next Friday corner infielders, the Friday after that catchers and outfielders and the final Friday will be pitchers, both starters and closers. We'll go over the youngsters that have shot up the rankings and the veterans who can and will still impact each of the positions.
